True meridians are generally preferred to magnetic meridians because
Survey is preferred with true meridian because true meridian remains constant. Magnetic Meridian: Vertical plane that passes through magnetic north and magnetic south is defined as Magnetic Meridian. Magnetic Meridian of a particular place changes with time.

The true bearing of a line is also called as azimuth.

See lessIf θ is the slope of the ground and l is the measured distance, the correction is
Slope correction: When you take a measurement with a tape along an inclined plane (along the natural slope of the ground). Obviously, the taped distance is greater than the horizontal distance, The difference between the slope distance and the horizontal distance is called the slope correction.

Plane table surveying is the graphical method of the survey in which the field observations and plotting are done simultaneously.

See lessAccuracy of 'fix' by two point problem, is
The two-point problem consists of locating the position of a plane table station on the drawing sheet by observation of two well defined points, whose positions have already been plotted on plan. The procedure of resection after orientation by two points is given below.

See lessWhile viewing through a level telescope and moving the eye slightly, a relative movement occurs between the image of the levelling staff and the cross hairs. The instrument is
Parallax: It is the relative motion of the image with respect to the cross hairs when the image formed by the object- glass does not fall in the plane of the diagram. It is due to faulty focusing of the object- glass, it can be tested by moving the eye up or down.

See lessIf L is the perimeter of a closed traverse, ΔD is the closing error in departure, the correction for the departure of a traverse side of length l, according to Bowditch rule, is
Bowditch's rule: The Bowditch Rule is a mathematical procedure used to bring the coordinates together. The relative error determined is then distributed to each coordinated point to compensate for the overall error. In general, this method is used to adjust closing error in a closed traverse.

See lessIn quadrantal bearing system, back bearing of a line may be obtained from its forward bearing, by
In a quadrantal bearing system, the back bearing of a line may be obtained from its forward bearing by changing the cardinal points, i.e., substituting N for S and E for W and vice-versa.

See lessThe limiting length of an offset does not depend upon
Offsets are the lateral distance of an object or ground feature measured from a survey line. The limiting length of an offset depends upon the accuracy of the work method of setting out perpendiculars, Scale of plotting, etc. It does not depend upon the Indefinite feature to be surveyed.
